just picked up an a/c 312. that's the good news. doing "google" trying to find out exactly what I've got isn't working too well.

so, need, ya'lls help in telling me what it is.

see attached pics

12hp Kohler, hydrostatic, trans, power hitch, electric clutch on nose of motor.

NO TAGS ANYWHERE I CAN FIND.

in pic 18, there is a vertical lever that I assume is the drive release, it don't budge. any suggestion on how to free it up?

I am currently working on a Landlord 101, no hydro but the same general design, and like yours mine has has been sitting for many years and has the same problem. I would remove the side panel as shown in the photo I marked up below, and soak it in PB Blaster or your favorite penetrating lubricant, then after letting it soak, use a hammer to get the pedal to move, spray in some more lubricant. and keep working it. If this doesn't work, take a torch and apply heat, making sure there are no combustibles like oil soaked dust and grass clippings near  where you are working. Rinse, wash, and repeat until the lever moves freely.

By the way, welcome to the club.

I think he's asking about the "freewheel" lever for the Vickers tranny. 

There were two types and they work opposite.  The early ones, like in my Homelite T-12, the brake doesn't work when in "freewheel".  Here's a pic of the instruction plate and you can see the lever end:

I believe your AC312 is the above type.  If you can't push the tractor easily with the lever in the position it's in, that would confirm.

The later type, in the "freewheel" position, the brakes work.  Here's a pic of that label and you can see the "freewheel" position is reversed:

All I can suggest to free it, is to spray with penetrating oil and rock the tractor back and forth while applying some pressure to the lever. 

If the tractor has sat in the weather water may have gotten inside and rusted parts together.  I believe this is the problem rfsmith ran into; I'm pretty sure he posted about opening up the case to repair the problem, but the only post I can find is about putting it back together:

With hydrostatic transmission, you would have an A/C 312H. I have an A/C 414S with a shuttle transmission. They are close cousins and the red-headed step children to the rest of the club. Welcome, Dave

I did a quick search (home page, spy glass in upper right orange ribbon) for 312d: https://simpletractors.com/search/  7 pages of threads & some interesting stuff here (this is one I don't know much about). This specs post is helpful to id: https://simpletractors.com/research/allis-chalmers/ac-300-series/1971-catalog/300_specs/

Keep those update pics & posts coming. Looking forward to reading your progress.

Not really sure on the exact capacity but I fabbed one up on my 7117 using an electric lift from a tractor just like yours. I had a 10" moldboard plow on the back and it lifted it with ease until the welds on my custom bracket broke(It was only my 2nd or 3rd time welding... The weld looked terrible and I'm surprised it lasted as long as it did).

Elliott, pretty weld doesn't actually mean it's stronger, practice makes perfect 666

My Grandpa used to say "If you can't weld good, weld a lot".

      Hello glad I got on this site. I hope to upload a couple of photos of my Simplicity Broadmoor 
      Model 707 Tractor. I have replaced all the belts on it and installed a new ignition switch.
      Have a mower deck which was in poor shape , repaced a couple of bushings and welded the
      deck where there was some holes. The tractor and mower deck came from a friend and the 
      mower deck metal was getting pretty thin. Some new metal was put in it and we also undercoated the underside of the deck. This was done by my friend Greg Toulman.
      I have not put the mower deck on the tractor yet, waiting for Greg to come home and give me a hand. Can you please tell me if there is a manual for the mower deck and where I could get one.
      I would also like to get some moon wheel discs as well.
      I will try and down load some photos of the tractor when my wife shows me how to. 
      I really love driving this tractor and also how well it is made compare today's tractors, especially the flexible rear end and the rollers.
      Tell the next time 
      Paul

      I assume it's a bosche, correct
